[babel] info and data models -- feedback requested

["STARK, BARBARA H" <[e-mail]>]

There are 2 items related to the info/data models that have been swirling around in my head over the past month. 

1. Since the most recent drafts of rfc6126bis now have 2 examples of initial interval settings (for cases where fast convergence is desired, or where slow convergence is acceptable and less chattiness is desired), I don't like that we have no means for the user to express what their preference is around this (in case an implementation could support both cases). Should we have something at the top level of the model like:
boolean                rw converge-fast;

   converge-fast:  Indicates whether the user wants the network to converge 
      quickly (which will cause Babel messages to be sent more frequently), or
      prefers fewer Babel messages with slower time to convergence.  Fast
      convergence is desired if "true". An implementation MAY choose to expose
      this parameter as read-only ("ro").

2. In BBF, I got a comment related to babel-stats-enable and babel-packet-log-enable. It's unspecified as to whether previous data is discarded when the stats or log are enabled, or the new log entries are appended / existing counts incremented. I tend to agree that the lack of a statement will lead to inconsistency, and would prefer consistent behavior. Mahesh and I had a brief exchange where we disagreed on what the preferred behavior should be -- which suggests there is definitely a strong likelihood of different implementations choosing different behavior in the absence of guidance.

I realize we're past last call. But I think these are important.
